** GSoC2009 **
A GSoC2009 project is underway to improve Tcl's support for reading raster and
vector geospatial data formats, as well as rendering them in a Tk canvas
widget. Project's detailed description and status updates can be found at:
[The tcl-map GSoC2009 project]. The source code is hosted at:

** Misc **
[CL] has lots of toy maps (of US states, Norway, the Volga River, ...) written as
Tcl programs, with "live" canvases, ... He's trying to figure out
how to package them so others can see them. A hint of what's possible appears in
"Open Cartography" [http://swexpert.com/CC/SE.C12.NOV.01.pdf].
[Zarutian] is thinking about scanning and vectorizing several free maps of Iceland's Captialzone (?? Capital city/zone ??).
